July 25.--We travelled N. 60 degrees W. and, at two miles, reached a salt-water creek, which we crossed at a fishing place of the natives. Soon afterwards we came on other shallow half dry salt-water creeks, the dry parts of which were covered with thick incrustations of salt, some of which we collected. Our bullocks were very seriously bogged in crossing one of them. After passing this intricate meshwork of boggy channels, we entered upon an immense plain, with patches of forest appearing here and there in the distance. It was well grassed, but its sandy patches were covered with Salicornia. This plant abounded particularly where the plain sloped into the system of salt-water creeks; the approaches of which were scattered over with the raspberry-jam tree. A west-north-west and west course led me constantly to salt water; and we saw a large expanse of it in the distance, which Charley, to whose superior sight all deference was paid, considered to be the sea. I passed some low stunted forest, in which a small tree was observed, with stiff pinnate leaves and a round fruit of the size of a small apple, with a rough stone, and a very nauseous rind, at least in its unripe state. To the westward of this belt of forest, we crossed extensive marshes covered with tender, though dry grass, and surrounded by low Ironstone ridges, openly timbered with stunted silver-leaved Ironbark, several white gums, and Hakea lorea, R. Br. in full blossom. We had not seen the latter for a long time, although Grevillea mimosoides, with which it was generally associated, had been our constant companion.
